I think the calendar space isn't nearly as flooded as social bookmarking.

The most interesting proponent I've seen in the calendar space is [TouchBase](http://itunes.apple.com/us/app/touchbase-calendar-1-touch/id...).

I haven't seen a social bookmarking proponent that I really liked, and something like Instagram for links would be really interesting. I say this because it's not a social sharing app that blasts everything you do out to your entire social network on facebook (unless you set it to), and you don't automatically follow every one of your friends that's on Instagram. That's really nice, because the apps that make those assumptions are immediately filled with garbage from those with whom I have not interacted in years.

I'm sure you already have your ideas, but I figured I'd throw this out there for you to add to your melting pot of responses.

Actually, I have an alpha social bookmarking product that is something like this. The home page is crap and I am in the midst of something else so I can get to it for a week. but it has the features you mention. I have been keeping it under wraps but if you want to crawl around in it for fun its located at www.markmyplace.com. feedback appreciated.

Thanks a lot for your response. The social bookmarking app that we are think of mainly addresses the issue of noise. We are envisioning a closed network for sharing content.
